Gang, I am looking for exhaust upgrade for my 09 TE510. my stock pipe just sounds so damn loud.. I bought the bike used and power up kit was already installed, so I dont really know what if anything was done to the pipe other than removing the cat. here are the requirements in order of priority. 1. has to be quiet. I am over the age where atracting attention is required. especially in my riding area 2. I could use some more power when I am in sumo mode please let me know what options are out there! thanks!
